  2. 1. High-order finite difference approximations for hyperbolic problems : multiple penalties and non-reflecting boundary conditions

    Author : Hannes Frenander; Jan Nordström; Philipp Birken; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis, we use finite difference operators with the Summation-By-Partsproperty (SBP) and a weak boundary treatment, known as SimultaneousApproximation Terms (SAT), to construct high-order accurate numerical schemes.The SBP property and the SAT’s makes the schemes provably stable.

  4. 2. Electrostatic Interactions in Coarse-Grained Simulations : Implementations and Applications

    Author : Yong-Lei Wang; Aatto Laaksonen; Christian Holm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissipative particle dynamics; electrostatic interaction; ionic liquid; coarse-grained model; fysikalisk kemi; Physical Chemistry;

    Abstract : Electrostatic interactions between charged species play a prominent role in determining structures and states of physical system, leading to important technological and biological applications. In coarse-grained simulations, accurate description of electrostatic interactions is crucial in addressing physical phenomena at larger spatial and longer temporal scales. READ MORE

  5. 3. Dynamics of Ca2 handling in vascular smooth muscle

    Author : Karl Dreja; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smooth muscle; phenotypic modulation; caveolae; Physiology; confocal microscopy; calcium; Fysiologi;

    Abstract : Intracellular Ca2+ is a key regulator of vascular contractility, and thereby of blood perfusion and pressure. Ca2+ signals are essential also for cell migration, proliferation and regulation of numerous enzymes. READ MORE

  6. 4. Adaptations for nocturnal vision in insect apposition eyes

    Author : Birgit Greiner; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; temporal and spatial summation; optical and neural adaptations; theoretical modelling.; Djurs anatomi och morfologi; Zoologi; dim light; vision; landmark navigation; nocturnal bees and wasps; Zoology; Animal anatomy; animal morphology;

    Abstract : Due to our own preference for bright light, we tend to forget that many insects are active in very dim light. The reasons for nocturnal activity are most easily seen in tropical areas of the world, where animals face severe competition for food and nocturnal insects are able to forage in a climate of reduced competition and predation.

  7. 5. Dendritic and axonal ion channels supporting neuronal integration : From pyramidal neurons to peripheral nociceptors

    Author : Marcus Petersson; Erik Fransén; Theodore Cummins; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ion channels; computational modeling; simulations; dendrites; axons; TRP; hippocampus; C-fiber nociceptors; pain;

    Abstract : The nervous system, including the brain, is a complex network with billions of complex neurons. Ion channels mediate the electrical signals that neurons use to integrate input and produce appropriate output, and could thus be thought of as key instruments in the neuronal orchestra. READ MORE
